Claims. (CI. 20-62) More specifically,

yet so as, at the same time, to permit adequate ventilation. Theprincipal difficulty with the prior louver constructions has related totheir cost. Because a plurality of window panes are employed in eachwindow construction and each of these panes had to be supported uponseparately formed bearing elements, the window constructions arerelatively expensive. Further, the presence of intricate leverconstructions in windows of this type has frequently caused manydifiiculties for the average householder for, once one of the panes inthese windows has become jammed for some reason, it is usually beyondthe capacity of the average individual to repair the construction.

It is an object of the present invention to overcome the foregoing andrelated defects of the prior louver window constructions. A furtherobject of the invention is to produce a new and improved type of louverwindow construction which is relatively inexpensive, which is relativelyfoolproof, and which can be easily and c0nveniently manufactured.Further objects of the present invention, as well as the advantages ofit, will be apparent from this specification, the appended claims, andthe accompanying drawings, in which:

Fig. 1 shows a front view of a louver window in accordance with theinvention;

Fig. 2 is an expanded isometric sectional view illustrating theconstruction of the pivot joint used in the window of Fig. 1;

Fig. 3 is a sectional view of the window of Fig. 1 taken at line 3--3 ofFig. 1;

Fig. 4 is a partial sectional view of the jamb of the invention taken inthe direction of the arrow 4 indicated in Fig. 3;

Fig. 5 is a similar partial sectional view taken in the direction of thearrow 5 of Fig. 4; and

Fig. 6 is a sectional view taken at line 66 of Fig. 5.

Briefly, the above and related aims are achieved by forming a louverwindow construction utilizing a variety of stamped parts of a specificshape holding the window panes employed, and utilizing further anovercenter toggle-lock arm construction to control the movement of allof these panes in unison. Perhaps this type of construction will be bestseen with reference to the figures of the drawings.

Fig. 1 shows a new window 10 of the invention comprising a plurality ofpanels including glass panes 11 having recessed side portions 12 and 13,as is best shown in Fig. 3. The ends of these panes are disposed withinappropriate metal channels 15 having pairs of ear-shaped lugs 16 of thetype clearly illustrated in Fig. 2. Each pair of lugs 16 is adapted tofit within complementary openings 18 positioned within a bushing 19having a depressed boss portion 20 (Fig. 6) and a crank arm comprisingan outwardly ofiset shank portion 21 and a pivot portion 22 providedwith an aperture 23. These bushings 19 are adapted to fit within bearingopenings 26 within jambs 27 of the windows of the invention. These jambs27 are composed of a central portion 28 and side flanges 29 projectingaway from the glass panes 11, concealing the entire bushing and lever orcrank construction, as will be more fully explained. The jamb ends 30are connected together by means of appropriate top and bottom connectingpieces 31. These pieces may be formed in the U-shaped manner in whichthe jambs 27 are formed, or may consist of other equivalent means.

In use, the lugs 16 are positioned within the openings 18 in thebushings 19 and are bent over on the sides of these bushings remote fromthe panes 11 in the manner clearly indicated in Figs. 4, 5 and 6 of thedrawings. When fixed in position, all of the bushings 19 in each of thejambs 29 are parallel to one another, and those in one of the jambs 29are connected to each other by means of a rod 35 and pivotal connections36, the rod being between the portions 22 of the crank arms and thecentral portion 28 of the corresponding jamb 27, as best shown in Fig.5. This rod 35 is attached by means of pivot 37 to a link 38 which inturn is connected by means of another pivot 39 to a handle 41 forgoverning the movement of the various glass panes 11. This handle 41 isattached to the jamb by means of a pivot 42 and is provided with a shankportion 43, as shown in Fig. 5, removed from the two pivots 39 and 42.and positioned at an angle to them through an aperture 45 in a flange29. This shank portion 43 is provided with means 44 for connecting theentire structure to an appropriate mechanism for governing the entiremovement of the window panes. Such mechanism is not shown inasmuch as itis of a category known to the art.

When all of the panes are assembled together in a closed relationship,as shown in Fig. 1, the handle 41 is normally disposed in the positionindicated in full lines in Fig. 5. To open these panes, the handle ismoved to the position shown in the phantom view of the same Fig. 5,causing the link 38 to move upward and in turn causing the rod 35 tomove in the same direction, rotating all of the bushings 19 in acounterclockwise direction as shown in the same figure. In this openposition, the pivot 39 is slightly above the pivot 42 in an over-centertype position. In this position, the handle 41 is locked againstrotation except when a force is placed upon it so as to return it andthe other elements shown to their original closed positions. In thisclosed position, it will be seen, as shown in Fig. 3, that the sections12 and 13 of adjacent glass panes fit together so as to form aweather-proof joint. The upper ends of the channels 15 are provided withslanting joints 17, as shown in Fig. 3 of the drawings, so as to providea clearly weather-proof construction.

Those skilled in the art will realize that the present invention iscapable of many modifications falling within the scope of thisdisclosure. Insofar as such modifications are covered by the appendedclaims, they are to be considered part of the present inventive concept.Those familiar with the field will realize that the present inventionmarks a substantial improvement in that the bushings and all the otherparts shown may be readily manufactured from simple aluminum stampingsor from readily available bar stock. Separate machining steps, asrequired in the prior art, are not required with the instantconstruction. Further, this, construction is relatively simple tomanufacture and is, in effect, foolproof.
